smb: client: handle lack of FSCTL_GET_REPARSE_POINT support
As per MS-FSA 2.1.5.10.14, support for FSCTL_GET_REPARSE_POINT is
optional and if the server doesn't support it,
STATUS_INVALID_DEVICE_REQUEST must be returned for the operation.
If we find files with reparse points and we can't read them due to
lack of client or server support, just ignore it and then treat them
as regular files or junctions.
Fixes: 5f71ebc41294 ("smb: client: parse reparse point flag in create response")
